Laparoscopic diagnosis and treatment of rectum telangiectasia: report of a rare form of lower gastrointestinal hemorrhage / 南方医科大学学报

We report a case of rectum telangiectasia, a rare form of lower gastrointestinal hemorrhage caused by vascular malformation. The patient underwent laparoscopic assisted abdomino-perineal resection of the sigmoid colon-rectum telangiectasia. The extent and degree of pathological changes were observed directly from the intestinal wall during laparoscopic surgery, and after collection of biopsy evidence, concomitant definitive surgery was performed to achieve a minimally invasive effect.
